Join with net_http_request table fails to get quals to do the HTTP queries

[e-gineer]

Thought I'd try joining the hackernews_new table with the net_http_request table to try and send slack messages for new items ... fun idea, but unfortunately it doesn't work because of the postgres plan. I couldn't find a way to trick it either.

with new_posts as (
  select
    '{"text": "' || title || '"}' as slack_msg
  from
    hackernews_new
  where
    time > now() - interval '1 min'
  order by
    time desc
)
select
  r.url,
  r.method,
  r.response_status_code,
  jsonb_pretty(r.request_headers) as request_headers,
  r.response_body
from
  net_http_request as r,
  new_posts as p
where
  r.url = 'https://hooks.slack.com/services/<redacted>/<redacted>/<redacted>'
  and r.method = 'POST'
  and r.request_body = p.slack_msg
  and r.request_headers = '{"content-type": "application/json"}'::jsonb

Here is the quals log I see:
